?How to use the PDF Compressor

1

Add your PDF

Drop the PDF you want to shrink into the box above.

2

Compress locally

Your browser reduces the file size on your device. Nothing is uploaded.

3

Download the smaller PDF

Save the compressed PDF and email or upload it easily.

Why compress

Many email and upload forms reject files above a few megabytes. A compressed PDF gets under those limits while remaining clear enough to read and print.

Private by design

The file is processed on your own device, so sensitive PDFs are never uploaded.

About the PDF Compressor

Large PDFs are a pain to email or upload because of attachment limits. Compressing a PDF reduces its file size so it fits within those limits while staying readable. Joy File Convert compresses your PDF locally in the browser, which is important for contracts, scans and other documents you would rather not upload to an unknown server.
